PHILIP ULMER, OF NEW YORK, N. Y.

SPRING- BED-BOTTOM.

Specification forming part of Letters Patent No. 25,689, dated October 4, 1859; Reissued March 13, 1860, N0. 929.

To all whom it may concern:

Be it known that I PHILIP ULMER, of the city, county, and state of New York, have invented an Improved Spring Bed- Bottom; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings.

The nature of this invention consists in an improved application or manner of attaching elastic webbing or other similar materials (used as a spring) to the rails and slats of a bedstead, forming a spring bottom to the same.

Figure 1 is a partial view of a bedstead having this improvement applied. Fig. 2 is a full size side view of the spring &c., partly in section. Fig. 3 is a top view, also partly in section.

A, represents the end rail of a bedstead, to which the slats B B are attached by means of springs of elastic webbing as be low explained. The slats are of the usual form and size and are attached at both their ends in the manner described for the one, all which will be well understood.

At 1), Figs. 1, 2 and 3 is shown the elastic webbing. This in itself is a well known article of manufacture and needs no further description. A link of metal fulfils the office of connecting the spring or webbing with the slat. It is thus connected by means of a screw which is a fixture while the slat is detachable or can be unhooked and removed at option. The webbing passes through this link, its two ends then joined are secured to each other or by a common fastening as follows: a, is a strip of metal, an inch or more in width, having its outer surface convex and its inner a corresponding concave leaving a space between it and the rail against the side of which it is screwed when in place, and in length may compass the entire series of slats, or only that of one, as at Fig. 3. It has apertures or slots of the proper size to receive the webbingwhich passes through it and is secured on its inside by means of a wedge or tongue of metal ((1,) which has at its head on either side a projecting thin edge turned inward and which is also serrated, that it may indent the webbing in some degree.

The two ends of the webbing being passed through the aperture -the tongue (0,) is then driven with such force as may be necessary between them, the effect of which it will be seen is first, by its action as a wedge to force the webbing in contact with the lips of the aperture, and secondly to bend the ends at a sudden angle and confine them in firm contact with the metal strips a, the thin propecting edges entering into the substance of the webbing, of themselves and in conjunction with the wedge serve to prevent any slip, rendering the parting "of the connection impossible. It is also so planned in thickness with reference to the several parts that when the strip a, is secured to the rail, the tongue 0, bears on its back part against the wood of the rail, effectually pre venting the attachment from getting loose while the strip is so secured. This dispenses with the necessity of uniting the ends of webbing by sewing which has hitherto been the only means; the substance of the webbing being of a nature difiioult to sew, and at best giving a bungling appearance, is also liable to part at any time when joined in such manner.

By the improved method herein proposed an attachment is obtained which in itself is simple and of the greatest possible strength of which the material will admit.

Different forms of wedge and serrated or sharpened edges will suggest themselves as modifications of the fastening above without changing substantially the effect. The strip a, may also be modified byinstead of the tubular shape, it may be flat and the attaching parts recessed into the rail.

Having thus described my invention what I claim therein as new and desire to secure by Letters Patent is:

The method herein described of connecting the spring I), or any equivalent means, by which the same is secured in place by contact between compressing surfaces substantially in the manner and for the purposes set forth.

PHILIP ULMER.
